This inventionhas for its object the provision of a cheap device whereby crude oil or distillate may be efficiently utilized as a fuel. The invention provides a device which may be employed within the, fire-box of an ordinary stove or in any manner external to a stove and without occupying a great deal of space will furnish av relatively large volume-of heat for cooking or heating. in The invention is illustrated in the .accom panying drawing and will be hereinafter fully set forth.

In the drawing: Figure 1 is a vertical section illustrating the burner mounted within the fire-box of a stove, and

Fig. 2 is a removed. V

Referring more particularly to Fig. 1, the numeral 1 indicates the top and the numeral 2 the front of a fire-box of a stove-which may have any desired form. For the most efficient use of my improved burner, a draft pipe 3 is fitted in the front of. the fire-box and extends inwardly and somewhat downwardly therefrom, while a fuel supply pipe perspective view of the burner 4 is secured in and extends through the top of the firebox and has itslower end disposed within a nipple 5, said nipple being in turn threaded through a boss 6 provided therefor on the top 7 of the burner. The burner may be formed of any suitable material and may be a casting or heavy gage sheet metal pressed or folded into the desired form, but, however it may be produced, it presents a hollow or tubular body 8 which will preferably be disposed in an inclined position, as shown in Fig. 1 of the drawing, and tapers towards its upper end.

At said upperend, a deflecting spreader'9 is provided, said spreader'consisting of. a plate extending laterally from each side of the body andcloubled or rolled on itself to provide an upper leaf 10, the edge of which is spaced from'the upper end of the top of 928. Serial' aaqazga;

the buraertouy; At its lower end, the bottom wall 11 "of the burner body is-carried downwardly beyond the plane of the greater p'ort ion'of the bottom "or backof the body is then carried forwardly and upwardly, as shown at 12, whereby the lower end of the tubular body" is fo'rmed'intdfacup or reservoir 13, the fuel 's'uppi1y;pipe i being located approximately over this reservoir d the upper portion of the reservoir being open, as indicated at l4c, whereby the en'db'f the draft pipe il maybe sodisp'ose'd-asto direct inflo wing air into ure interior of the ibu rnerbody.- The draft p'ipe maybe latitized to partly su portthe burne aii convenient brackets brother fastenings being .p'ro'vi ded to furnish needed additional su'pports. and secure the burner proper position. I I i[n use, asrrra'llqua ntity 03E kerosene or soine other easilyig'riited oil is placed-in th r'es'ervoir or cup .13 and is ignited by the usef0f-"a*"1r1'atfohfior other lighter. The burning of this oil will heat the 'w-alls of the burner bodyso that'the Bottom or lower portionzther f-wil l- Become highly heated and sferveasfla vapori ing plate; "When the consumption f-of th i's preliminary charge of oil has been completed, the fuel oil :is per mitlfedjto flow to the burner throug'h; the

supplypipe'd, it being und erstood that the fuel :is fed from-iasupplytank or reservoir 7 located lat/aproper distance from the burner V forsafetyiand fitted with a c'ut-off valve so that .the flow ofthe fuelmayibe setup latedl .Thepinfl'owin'g fuel: should be so 1 re: .stricted that it {will emerge from the supply pipe inqrlrop's which will-fall, atjfonc'e onto the heated bottom ?or 'vaporizing p'latei of the'burner bodysothat it will be at once ignited, an'd Y the draft E pipe 1 3. willja'dmit sufficient Fair to mingle with the; fuel "and form a proper. combustible iniiiture. Moreover, thetairgflowing in thr oughxtlie'draft so whenever; 'desiredand" maybe easily f regu pipe 3 will naturally flow up through the tapered tubular burner body and impinge against the deflecting spreader 9 so that it will be turned laterally to both sides of the burner. The flame caused by the ignition of the fuel will, of course, follow the inflowing air and it, too, will be spread at the upper end of the burner body by the U-shaped 0r grooved deflector, the upwardly tapered tubular body aiding in forming the proper draft, and the leaf 10 will turn the flame back upon the body and maintain that temperature thereof which will make for proper vaporization and combustion. While the fuel should be admitted in drops, the flow of the successive drops should be sufficiently rapid to maintain a substantially constant feed of fuel to the vaporizing plate so that there will be a constant steady flame flowing upwardly through the burner body and turned aside at the upper end thereof and heat will be distributed throughout the" fire-box of the stove or spread in all directions if the burner should be used in the open. The device is exceedingly simple in its construction 'and may be produced at a very low cost, and I form a reservoir having anopen top, an air draft pi e leading into said open top,a lateral deflecting flame spreader extending across the upper end of the burner body, and means in the top of, the body adjacent the air draft pipe and said reservoir foradmitting fuel thereto.

3. An oil burner comprising a' hollow inclined upwardlytapered open-ended body provided at its upper end with a flame spreader consisting of a plate extending lat V erally from each side of the burner body and havingjan overhanging leafextending from end to end thereof and directed toward and spaced from the end of the burner body.

4. An oil burner comprising an inclined upwardly tapered tubular body having its bottom wall turned upwardly at its lower" end to form an integral "oil-holding cup, the'upper end of the body' being open and an air inlet being provided in the upper adjacent and above the oilcup, .means'for delivering oil into the oilcup, and a flame spreader consisting of a plate doubled longitudinally upon itself from end to end and forming a lower leaf integral with the lower wall of the body at the upper end thereof and extending laterally from the opposite sides thereof and an upper leaf parallel with the lower leaf and having its, edge spaced from the open upper end of the body.

In testimony whereof I affix-my si nature.
